 * [ ] coding style
 * [ ] documentation: see [the documentation requirements](https://leanprover-community.github.io/contribute/doc.html)
 * [ ] for tactics:
     * [ ] tests
     * [ ] efficiency (make sure at least it&#x27;s not outrageously inefficient)
  * [ ] it fits the overall mathlib design
